Answer:
initial velocity=0
accelaration=3m/s2
t=8 sec
by position time equation we have
s=ut+1/2at square
=0×8+1/2×3×8×8
=96m
so,the answer is 96 m

Given :
Acceleration of boat = 3 m/s²
Time = 8 seconds
To Find :
The distance travelled by the boat during that time
Solution :
From second equation of motion ,
Where ,
u is initial velocity
t is time
a is acceleration
s is distance travelled
We have ,
u = 0 [starting from rest]
t = 8 sec
a = 8 m/s²
Substituting the values in the equation ,
Hence ,
The distance travelled by the boat during that time is 96 m.nit
